To enable the fetchmail service to retrieve e-mails set the environment variable ENABLE_FETCHMAIL to 1. Your docker-compose.yml file should look like following snippet:
...
environment:
- ENABLE_FETCHMAIL=1
...
Generate a file called fetchmail.cf and place it in the config folder. Your dockermail folder should look like this example:
├── config
│ ├── dovecot.cf
│ ├── fetchmail.cf
│ ├── postfix-accounts.cf
│ └── postfix-virtual.cf
├── docker-compose.yml
└── README.md
Configuration
A detailed description of the configuration options can be found in the online version of the manual page.
Example IMAP configuration
poll 'imap.example.com' proto imap
user 'username'
pass 'secret'
is 'user1@domain.tld'
ssl
Example POP3 configuration
poll 'pop3.example.com' proto pop3
user 'username'
pass 'secret'
is 'user2@domain.tld'
ssl
IMPORTANT: Don’t forget the last line: e. g. is 'user1@domain.tld'. After is you have to specify one email address from the configuration file config/postfix-accounts.cf.
More details how to configure fetchmail can be found in the fetchmail man page in the chapter “The run control file”.
Polling interval
By default the fetchmail service searches very 5 minutes for new mails on your external mail accounts. You can override this default value by adding this line to your fetchmail.cf.
set daemon 60
You must specify a numeric argument which is a polling interval in seconds. The example above polls every minute for new mails.
Debugging
To debug your fetchmail.cf configuration run this command:
./setup.sh debug fetchmail
For more informations about the configuration script setup.sh read the corresponding wiki page.
